What fusion process is occurring in the star Procyon B?
Answer:
Procyon B's progenitor star most likely had around 2.59 solar masses. Estimates suggest that the star spent about 680 million years on the main-sequence, fusing hydrogen in its core. It evolved into a giant and lost much of its mass due to stellar winds

What process is similar in both fermentation and cellular respiration?
electron transport chain
aerobic ATP production
glycolysis in the cytoplasm
hydrogen ion pumping
Answer:
glycolysis in the cytoplasm
Explanation:
~ Fermentation and cellular respiration are alike in that they both begin with a series of reactions known as glycolysis, which breaks glucose molecules into smaller pyruvate molecules. They are also similar in that during both processes, ATP is produced for the cell to use.

It is the factor resulting from the activities of a living being or of any living component in an environment, such as the actions of an organism that affect the life of another organism.
what organelle directs cellular activity and stores chromatin
Answer:
Typically, the nucleus is the most prominent organelle in a cell (Figure 1). The nucleus (plural = nuclei) houses the cell's DNA in the form of chromatin and directs the synthesis of ribosomes and proteins.
Explanation:
Nucleus is the potential organelle directs cellular activity and stores chromatin.
what are the function of nucleus in a cell ?Nucleus is the most integral component, a double membraned cell organelle which carry all genetic material of the cell.
It regulates the growth and reproduction of the cell as it contain the genetic information.
It involve in duplication of DNA in the nucleus called as DNA Replication by producing the copies of DNA .
It has a major role in cell division like mitosis and meiosis.
It is the site of transcription which produces different types of RNA from DNA.
A special site in the nucleus called the nucleolus a non-membrane-bound condensed region of chromatin involved in active ribosomal RNA synthesis.

Yellow light travels through a certain glass block at a speed of 3 * 108 m/s . The wavelength of the light in this glass is 3.81 * 10 - 7m . What is the frequency?
Answer:
f = 7.87×10¹⁴ Hz
Explanation:
Given data:
Speed of light = 3×10⁸ m/s
Wavelength of light = 3.81 ×10⁻⁷ m
Frequency of light = ?
Solution:
Formula:
Speed of wave = wavelength × frequency
Now we will put the values in formula.
3×10⁸ m/s = 3.81 ×10⁻⁷ m × f
f = 3×10⁸ m/s / 3.81 ×10⁻⁷ m
f = 0.787 ×10¹⁵ s⁻¹
s⁻¹ = Hz
f = 0.787 ×10¹⁵ Hz
f = 7.87×10¹⁴ Hz

The soybean and the fungus might die because both of them are depending their lives on the said crop and both of them are having competition in having the nutrients for their survival.
The soy beans might be damage and the products of the farmer will decrease.Hope this helps and if you could mark this as brainliest. Thanks!
What is the role of an enzyme in a reaction with the reaction ? would the reaction happen without an enzyme?
Answer:
Enzymes are not used up in a chemical reaction. Usually, the enzyme will “reset” and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction.
Explanation:
Enzymes serve a similar purpose for chemical reactions in an organism's body, which is to lower the amount of "activation energy" needed for a particular chemical reaction to occur. Without enzymes, many chemical reactions would occur at a much slower rate because the amount of activation energy required would be far greater.

Explanation:
Suppose insects that feed on the plants were placed inside the growth chamber as well. Predict how this might affect the levels of CO2 in the growth chamber. How does this model, on a smaller scale, represent the cycling of carbon through Earth's systems?
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the diagram illustrating the growth chamber. However, since insects also produce/exhale carbon dioxide (CO₂) as a waste product, the level of CO₂ in the growth chamber will increase since insects will serve as an additional source for the production of CO₂.
This model shows how carbon is been cycled though the earth's systems. The CO₂ released/exhaled by animals is been inhaled by plants and used for the production of food substance like glucose (through the process of photosynthesis). Animals eat these plants and then release carbon from these food sources as CO₂ which is taken up from the environment again by plants.
